Generally, the present disclosure provides a battery panel assembly including a right battery panel assembly and a left battery panel assembly configured for a material handling vehicle. The right battery panel assembly and the left battery panel assembly may enclose a battery compartment on the material handling vehicle and protect a battery within the battery compartment from environmental factors. In one non-limiting example, the battery may be a lithium-ion battery. Additionally, the battery panel assembly may act as a vehicle counterweight while providing for installation and alignment of a multi-layered cover over a battery compartment opening.

A battery panel assembly according to the present disclosure may include a first or right assembly and a second or left assembly. FIG. 1 illustrates one non-limiting example of a first or right battery panel assembly 100 according to one aspect of the present disclosure. The right battery panel assembly 100 may be configured to engage one side (e.g., a right side) of a battery compartment 50 on a material handling vehicle 60. The battery compartment 50 may house a battery assembly 70 and counterweight assembly 80. The right battery panel assembly 100 may include a right inner panel 102 and a right outer panel 104.

Each of the keyhole slots 112 may be configured to receive a fastener 114, which can be a screw, pin, rod, or any other suitable type of mounting hardware. In another non-limiting example, the right inner panel 102 may include more or less than two of keyhole slots 112 on the top portion 108 and/or the bottom portion 110, which may be configured to receive a corresponding number of fasteners. The plurality of keyhole slots 112, for example, may be configured to engage a protrusion, which facilitates securing and aligning the right inner panel 102 to the material handling vehicle 60 or the battery assembly 70.

The top portion 108 of the right inner panel 102 may include one or more fastening apertures 115 and a battery service cutout 116 dimensioned to allow a charger (not shown) to access a battery mounted charging connector 118 on the battery assembly 70, when the right battery panel assembly 100 is assembled and covering the right opening 106 of the battery compartment 50. In another non-limiting example, the battery service cutout 116 may include a removable cover. The removable cover, for example, may be removably coupled or hingedly connected to the right inner panel 102 to provide access to the battery mounted charging connector 118.

The bottom portion 110 of the right inner panel 102 may include an inner panel inspection hole 120 dimensioned to provide visual access to a battery retaining pin 122 to see that the battery assembly 70 has been secured to the counterweight assembly 80. The battery retaining pin 122 may be inserted through holes in the counterweight assembly 80 and the battery assembly 70, and may be retained by a pin. The bottom portion 110 of the right inner panel 102 may further include one or more clearance holes 124. In the illustrated non-limiting example, the bottom portion 110 includes two clearance holes 124 that are laterally separated from one another. Each of the clearance holes 124 may be configured to receive a fastener 126, which can be a screw, pin, rod, or any other suitable type of mounting hardware. In another non-limiting example, the right inner panel 102 may include a plurality of clearance holes in the top portion 108 and/or the bottom portion 110 each configured to receive a fastener.

Additionally, the bottom portion 110 of the right inner panel 102 may include a notch 127 that facilitates lifting and removal of the right inner panel 102 from the material handling vehicle 60. In some applications, the notch 127 may provide access to a remote grease fitting (not shown) on the material handling vehicle 60.

Each of the clearance holes 134 may be configured to receive a fastener 136, which can be a screw, pin, rod, or any other suitable type of mounting hardware. In another non-limiting example, the right outer panel 104 may include a plurality of clearance holes in the top portion 128 and/or the bottom portion 130 each configured to receive a fastener. Further, the top portion 128 may include a charge connector access door 138. The charge connector access door 138 may be hingedly connected or removably coupled to the right outer panel 104. The charge connector access door 138 may cover a cutout 140 dimensioned to allow the charger to access the battery mounted charging connector 118 on the battery assembly 70 when the right battery panel assembly 100 is fully assembled and covering the right opening 106 of the battery compartment 50. In other words, the cutout 140 is configured to align with the battery service cutout 116.

The bottom portion 130 of the right outer panel 104 may include at least one keyhole 144. In the illustrated non-limiting example, the bottom portion 130 of the right outer panel 104 may include two keyholes 144 that are laterally separated from one another. Each of the keyholes 144 may be configured to receive a fastener 146, which can be a screw, pin, rod, or any other suitable type of mounting hardware. In the illustrated non-limiting example, the keyholes 144 may be configured to engage the fasteners 146, which are configured as a protrusion from the right inner panel 102. In another non-limiting example, the right outer panel 104 may include a plurality of keyhole slots on the top portion 128 and/or the bottom portion 130 each configured to receive a fastener.

The bottom portion 130 of the right outer panel 104 may further include a lifting hole 152 that may facilitate the installation and removal of the right outer panel 104 to the material handling vehicle 60. In the illustrated non-limiting example of FIG. 1, the lifting hole 152 may be substantially centered in the bottom portion 130 of the right outer panel 104, however, other configurations are possible. For example, the lifting hole 152 may be located at various locations along the top portion 128 or the bottom portion 130 of the right outer panel 104. The lifting hole 152 may alternatively be configured as a notch similar to notch 127 in the right inner panel 102. In some applications, the lifting hole 152 may provide access to a remote grease fitting (not shown) on the material handling vehicle 60.

The bottom portion 130 of the right outer panel 104 may further include an outer panel inspection hole 154 that aligns with the inspection hole 120 on the right inner panel 102, which may provide visual access to the battery retaining pin 122 to see that the battery assembly 70 has been secured to the counterweight assembly 80.

The right edge 132 of the right outer panel 104 may include a sensor target bracket 156. The sensor target bracket 156 may be used to verify that the right battery panel assembly 100 has been installed before operation of the material handling vehicle 60. The sensor target bracket 156 may be detected by a sensor on the material handling vehicle 60. In other non-limiting examples, the sensor target bracket 156 may be located on any of the sides of the right outer panel 104.

To assemble the first or right battery panel assembly 100, the right inner panel 102 may initially be coupled to one side of the battery assembly 70. For example, the right inner panel 102 may be installed onto one side of the battery assembly 70, such that the fasteners 114 extend through the keyhole slots 112. With the fasteners 114 installed within the keyhole slots 112, the right inner panel 102 may be supported on the side of the battery assembly 70. The fasteners 126 may then be inserted through the clearance holes 124 and be fastened to, for example, a threaded aperture on the side of the battery assembly 70 to fasten the right inner panel 102 to the battery assembly 70.

With the right inner panel 102 installed onto the battery assembly 70, the right outer panel 104 may be installed onto the right inner panel 102, thereby covering the right opening 106 and substantially enclosing the side of the battery assembly 70. For example, the right outer panel 104 may be installed onto the right inner panel 102, such that the fasteners 146 extend through the keyholes 144. With the fasteners 146 installed within the keyholes 144, the right outer panel 104 may be supported on the right inner panel 102. The fasteners 136 may then be inserted through the clearance holes 134 and be fastened to the fastening apertures 115 on the right inner panel 102 to fasten the right outer panel 104 to the right inner panel 102.

During assembly, the notch 127 and the lifting hole 152 may be used to support the right inner panel 102 and the right outer panel 104, respectively. For example, a crane, a lift, a jack, or another form of support may be coupled to the notch 127 and the lifting hole 152 during assembly.

As illustrated in FIG. 2, when the first or right battery panel assembly 100 is installed onto the battery assembly 70, the right outer panel 104 is generally received within the right opening 106 to enclose the battery assembly 70. In general, the right inner panel 102 may weigh more than the right outer panel 104, for example, due to the right inner panel 102 being fabricated from a material with a higher density. In this way, for example, the right inner panel 102 may serve as an additional counterweight. In one non-limiting example, the right inner panel 102 may be fabricated from a steel material, however, other materials are possible. For example, the right inner panel 102 may be fabricated from ductile iron. The weight of the right inner panel 102 may be varied by adding or removing material to the right inner panel 102 to add weight to the material handling vehicle 60. The right inner panel 102 may also provide additional protection to the battery assembly 70.

In one non-limiting example, the right outer panel 104 may be fabricated from a steel material, however, other configurations are possible. For example, the right outer panel 104 may be fabricated from a relatively lighter weight material such as aluminum or plastic. The right outer panel 104 may provide the battery compartment 50 with additional protection for the battery assembly 70 of the material handling vehicle 60. In addition, the right outer panel 104 may selectively provide access to components of the battery assembly 70, as needed. For example, the access door 138 may be manipulated to selectively provide access to the battery mounted charging connector 118.

Each of the clearance holes 234 may be configured to receive a fastener 236, which can be a screw, pin, rod, or any other suitable type of mounting hardware. In another non-limiting example, the left outer panel 204 may include a plurality of clearance holes in the top portion 228 and/or the bottom portion 230 each configured to receive a fastener.

The top portion 228 may include an access panel 238. The access panel 238 may have at least one mounting hole 242 to receive at least one fastener 243. In the illustrated non-limiting example, the access panel 238 includes two mounting holes 242 that are laterally separated from one another and each configured to receive a fastener 243. The access panel 238 may be removably coupled to the left outer panel 204 via the fasteners 243. The access panel 238 may cover a cutout 240 on the top portion 228. The cutout 240 may be configured to selectively provide access to the display 218 and the service ports 219 on the battery assembly 70, when the left battery panel assembly 200 is fully assembled. In other words, the cutout 240 is configured to align with the battery service cutout 216 and may be selectively removed from the left outer panel 204. In another non-limiting example, the access panel 238 may be hingedly or slidably coupled to the left outer panel 204.

The bottom portion 230 of the left outer panel 204 may include at least one keyhole 244. In the illustrated non-limiting example, the bottom portion 230 of the left outer panel 204 may include two keyholes 244 that are laterally separated from one another. Each of the keyholes 244 may be configured to receive a fastener 246, which can be a screw, pin, rod, or any other suitable type of mounting hardware. In the illustrated non-limiting example, the keyholes 244 are configured to engage the fasteners 246, which are configured as a protrusion from the left inner panel 202.

The bottom portion 230 of the left outer panel 204 may further include a lifting hole 252 that may facilitate the installation and removal of the left outer panel 204 to the material handling vehicle 60. In the illustrated non-limiting example of FIG. 3, the lifting hole 252 may be substantially centered in the bottom portion 230 of the left outer panel 204, however, other configurations are possible. For example, the lifting hole 252 may be located at various locations along the top portion 228 or the bottom portion 230 of the left outer panel 204. The lifting hole 252 may alternatively be configured as a notch similar to notch 227 in the left inner panel 202.

The left edge 232 of the left outer panel 204 may include a sensor target bracket 256. The sensor target bracket 256 may be used to verify that the left battery panel assembly 200 is installed before operation of the material handling vehicle 60. The sensor target bracket 256 may be detected by a sensor on the material handling vehicle 60. In other non-limiting examples, the sensor target bracket 256 may be located on any of the sides of the left outer panel 204.

To assemble the second or left battery panel assembly 200, the left inner panel 202 may initially be coupled to one side of the battery assembly 70. For example, the left inner panel 202 may be installed onto one side of the battery assembly 70, such that the fasteners 214 extend through the keyhole slots 212. With the fasteners 214 installed within the keyhole slots 212, the left inner panel 202 may be supported on the side of the battery assembly 70. The fasteners 226 may then be inserted through the clearance holes 224 and be fastened to, for example, a threaded aperture on the side of the battery assembly 70 to fasten the left inner panel 202 to the battery assembly 70.

With the left inner panel 202 installed onto the battery assembly 70, the left outer panel 204 may be installed onto the left inner panel 202, thereby covering the left opening 206 and substantially enclosing the side of the battery assembly 70. For example, the left outer panel 204 may be installed onto the left inner panel 202, such that the fasteners 246 extend through the keyholes 244. With the fasteners 246 installed within the keyholes 244, the left outer panel 204 may be supported on the left inner panel 202. The fasteners 236 may then be inserted through the clearance holes 234 and be fastened to the fastening apertures 215 on the left inner panel 202 to fasten the left outer panel 204 to the left inner panel 202.

During assembly, the notch 227 and the lifting hole 252 may be used to support the left inner panel 202 and the left outer panel 204, respectively. For example, a crane, a lift, a jack, or another form of support may be coupled to the notch 227 and the lifting hole 252 during assembly.

As illustrated in FIG. 4, when the second or left battery panel assembly 200 is installed onto the battery assembly 70, the left outer panel 204 is generally received within the left opening 206 to enclose the battery assembly 70. In general, the left inner panel 202 may weigh more than the left outer panel 204, for example, due to the left inner panel 202 being fabricated from a material with a higher density. In this way, for example, the left inner panel 202 may serve as an additional counterweight. In one non-limiting example, the left inner panel 202 may be fabricated from a steel material, however, other materials are possible. For example, the left inner panel 202 may be fabricated from ductile iron. The weight of the left inner panel 202 may be varied by adding or removing material to the left inner panel 202 to add weight to the material handling vehicle 60. The left inner panel 202 may also provide additional protection to the battery assembly 70.

In one non-limiting example, the left outer panel 204 may be fabricated from a steel material, however, other configurations are possible. For example, the left outer panel 204 may be fabricated from a relatively lighter weight material such as aluminum or plastic. The left outer panel 204 may provide the battery compartment 50 with additional protection for the battery assembly 70 of the material handling vehicle 60. In addition, the left outer panel 204 may selectively provide access to components of the battery assembly 70, as needed. For example, the access panel 238 may be selectively removed to provide access to the display 218 and the service ports 219.

It is to be appreciated that each of the inner panels and outer panels can be made of various materials. For example, the inner panels can be a casting of steel or ductile iron, as non-limiting examples. The outer panels can be a lighter weight material. For example, the outer panels can be made from aluminum or plastic, as non-limiting examples.
